To all whom it may concern:

Be it known that I, FRANK SMITH a citizen of the United States, residingat dlinton, in the county of Henry and State of Missouri, have inventedcertain new and useful Improvements in Wrenches; and I do declare thefollowing to be a full, clear, and exact description of theinventiomsuch as will enable others skilled hi the art to which it apertains to make and use the same.

it y invention relates to improvements in wrenches; and it consists inthe novel construction, combination, and arrangement of devices hereinshown and described. o

The object of the invention is to provide a more simple, durable, andeilicient wrench which may be convenientl used'as a pair of pliers, andfor various ot ier purposes.

The above and other objects which will 1 appear as thelnature of myinvention isbetter understood, are accomplished by means of theconstruction illustrated in the accompanying drawings, in which- Figure1 is a side view of my improved wrench, showin the hand-lever in itsnormal position, ig. 2 is a sectional view ShOWlIlg the lever swungoutwardly. Fig, 8 is a sectional view taken on the line 1+1 of Fi 1. Fi4 is a sliding catch'or lock for t e handever. Fig. dis a piece oftempered steel used as a spring). v

Referring to my drawings y numerals, 8 denotes my im roved wrench, whichcomprises a shank [havin a fixed-jaw}, a slot 5 at each si e of w ichforab'out onehalf'its length'arethreaded mam f 16, 17. Runningshdinglydn this slot s a shaft 12, at one end of which is pivotallymounted hand-lever. 19i which has form atone en a jaw 20, an alongitudinal sl t 21; Ex-

. tending from this slot to the and at the handlever is a grooved center22, which lies over i a portion of the shank 4, when" the handthe spring3, the grooved tron; In the shaft lever is in its normal 12, is a slot28, in wh ch is' the catch 2, and

art of patch 2 extending over the a ring a each-side; the spring beinform in a'curved manner serves to he (1 the catch 2 where placed. A

certain portion of catch 2, and spring 8, ex- 60 tending into the slot21 of the lever 19, serves to hold the catch 2 and the sprin 8 in theslot 23; The members 24, 25 o the catch 2, extend outward on o positssides to form a look when pushed ibrward into the recesses 10, 11 formedin the lever 19, the lever is locked; normal position for useof. thetool as afwrench.

Extendin from one end of the shaft 12,

is a pivot 2 extendin throu h the center portion of a. screw 2 whic isheld on pivot 27 by a screw head 29, the threaded portion of the screw28, running in the threaded members 16, 17.- By turning the screw 28 tothe right the jaw 20 will coact 5 with the 'aw 7,1and if to the left itwill se arate thenjawp; 4

\ econ on, use, and advantages of" the invention will be readilyunderstood from the foregoing description, taken in connection wit theaccompanyingl drawings. It will be seen that when e lever is locked dthe tool is to be used as a wrench, th lever then forms a part of thehandle iaof e wrench, thereby being out of the we when used in closeplaces. When the jaws are separated to recelve a large nut,

it will he observed that the same leverage ma 'be gfiilied as when thejaws are toct er. e movable jaw being a part of so "a lever there is nochance for play when worln'ng on small or worn nuts. The adjusting screwoperating in a thread at each of its op to sides, is stronger, moredurable and can not buckle. The Wrench can be made with less bulk,weight and cost for agiven strength.

1am aware that prior to my inventlon wrenches wi lever attachments havebeen used I there ore do not claim the combina- 0 tron broadly; but whatI claim as new, and desiredito b Letters Patent, is-

A wrench comprising a shank having a fixed jaw at one end and havin alongitudinal slot therein, part of which slot is threaded, a shaftshdmgly engaged in said slot and provided with a rectangular opening, ascrew swiveled on one end of said shaft and adapted to engage thethreads of said shank, a longitudinal y grooved lever pivotnllyconnected to said shaft and provided with a slut through which saidshenk is adapted to extend, said lever having re messes on either side,a jaw formed integral with said lever, a atch slidingly engaged to en esaid the le recesses and thereby hold 10 yet in fixed position relativeto the shank, and a spring frietionally engaged with said catch.
